Detailed Description

Items that can be configured for a Session.

Some Session Properties can also be set as environment variables. If a session property can be set as an environment variable, the API will only look for that environment variable if the property is not specified in the sesssion property list passed to solClient_session_create.

The following environment variables are recognized:


Define Documentation

#define SOLCLIENT_SESSION_PROP_ACK_EVENT_MODE   "SESSION_ACK_EVENT_MODE"

This property specifies if a session event SOLCLIENT_SESSION_EVENT_ACKNOWLEDGEMENT acknowledges a single message (see SOLCLIENT_SESSION_PROP_ACK_EVENT_MODE_PER_MSG) or a range of messages (see SOLCLIENT_SESSION_PROP_ACK_EVENT_MODE_WINDOWED).

Default: SOLCLIENT_SESSION_PROP_ACK_EVENT_MODE_PER_MSG.
Setting this property to SOLCLIENT_SESSION_PROP_ACK_EVENT_MODE_WINDOWED will not affect RejectedMessageError events, they will still be emitted on a per message basis.

#define SOLCLIENT_SESSION_PROP_AD_PUB_ROUTER_WINDOWED_ACK   "SESSION_AD_PUB_ROUTER_WINDOWED_ACK"

When disabled, initiate a window size of 1 to appliance, but do not wait for acknowledgments before transmitting up to the actual window size.

Default: SOLCLIENT_SESSION_PROP_DEFAULT_AD_PUB_ROUTER_WINDOWED_ACK

#define SOLCLIENT_SESSION_PROP_APPLICATION_DESCRIPTION   "SESSION_APPLICATION_DESCRIPTION"

A string that uniquely describes the application instance.

Default: SOLCLIENT_SESSION_PROP_DEFAULT_APPLICATION_DESCRIPTION

#define SOLCLIENT_SESSION_PROP_BIND_IP   "SESSION_BIND_IP"

(Optional) The hostname or IP address of the machine on which the application is running.

On a multihomed machine, it is strongly recommended to provide this parameter to ensure that the API uses the correct network interface at Session connect time. Default: SOLCLIENT_SESSION_PROP_DEFAULT_BIND_IP

#define SOLCLIENT_SESSION_PROP_BLOCK_WHILE_CONNECTING   "SESSION_BLOCK_WHILE_CONNECTING"

Use SOLCLIENT_PROP_ENABLE_VAL to block the calling thread on operations such as sending a message, subscribing, or unsubscribing when the Session is being connected or reconnected.

The operation must already be blocking (see SOLCLIENT_SESSION_PROP_SEND_BLOCKING and SOLCLIENT_SESSION_PROP_SUBSCRIBE_BLOCKING). Otherwise, SOLCLIENT_NOT_READY is returned if the Session is being connected. Default: SOLCLIENT_SESSION_PROP_DEFAULT_BLOCK_WHILE_CONNECTING

#define SOLCLIENT_SESSION_PROP_BLOCKING_WRITE_TIMEOUT_MS   "SESSION_WRITE_TIMEOUT_MS"

The timeout period (in milliseconds) for blocking write operation.

The valid range is > 0. Default: SOLCLIENT_SESSION_PROP_DEFAULT_BLOCKING_WRITE_TIMEOUT_MS

#define SOLCLIENT_SESSION_PROP_BUFFER_SIZE   "SESSION_BUFFER_SIZE"

The maximum amount of messages to buffer (in bytes) when the TCP session is flow controlled (see Message Buffer Size Configuration).

The valid range is > 0. Default: SOLCLIENT_SESSION_PROP_DEFAULT_BUFFER_SIZE

#define SOLCLIENT_SESSION_PROP_CALCULATE_MESSAGE_EXPIRATION   "SESSION_CALCULATE_MESSAGE_EXPIRATION"

If this property is true and time-to-live (solClient_msg_setTimeToLive()) has a positive value in a message, the expiration time is calculated when the message is sent or received and can be retrieved with solClient_msg_getExpiration.

#define SOLCLIENT_SESSION_PROP_CLIENT_MODE   "SESSION_CLIENT_MODE"

Deprecated.

The CCSMP API detects the appliance capabilities, so it is no longer necessary to specify to use 'clientMode' or not. This property is ignored when specified.

#define SOLCLIENT_SESSION_PROP_CLIENT_NAME   "SESSION_CLIENT_NAME"

The Session client name that is used during client login to create a unique Session.

An empty string causes a unique client name to be generated automatically. If specified, it must be a valid Topic name, and a maximum of 160 bytes in length. For all appliances (SolOS-TR or SolOS-CR) the SOLCLIENT_SESSION_PROP_CLIENT_NAME is also used to uniquely identify the sender in a message's senderId field if SOLCLIENT_SESSION_PROP_GENERATE_SENDER_ID is set. Default: SOLCLIENT_SESSION_PROP_DEFAULT_CLIENT_NAME

Examples:
ex/ios/examples/SubscribeOnBehalfOfClientExample.m, and ex/subscribeOnBehalfOfClient.c.
#define SOLCLIENT_SESSION_PROP_COMPRESSION_LEVEL   "SESSION_COMPRESSION_LEVEL"

Enables messages to be compressed with ZLIB before transmission and decompressed on receive.

The valid range is 0 (off) or 1..9, where 1 is less compression (fastest) and 9 is most compression (slowest). Default: SOLCLIENT_SESSION_PROP_DEFAULT_COMPRESSION_LEVEL

Note: If no port is specified in the SESSION_HOST property, the API will automatically connect to either the default non-compressed listen port (55555) or default compressed listen port (55003) based on the specified COMPRESSION_LEVEL. If a port is specified in the SESSION_HOST property you must specify the non-compressed listen port if not using compression (compression level 0) or the compressed listen port if using compression (compression levels 1 to 9).

Examples:
ex/common.c, ex/directPubSub.c, ex/ios/Example.m, ex/ios/examples/DirectPubSubExample.m, ex/ios/examples/TopicDispatchExample.m, ex/perfADPub.c, ex/perfADSub.c, ex/perfTest.c, ex/RRDirectReplier.c, ex/RRDirectRequester.c, ex/RRGuaranteedReplier.c, ex/RRGuaranteedRequester.c, and ex/topicDispatch.c.
#define SOLCLIENT_SESSION_PROP_CONNECT_BLOCKING   "SESSION_CONNECT_BLOCKING"

Use SOLCLIENT_PROP_ENABLE_VAL to enable blocking connect operation.

A blocking connect operation suspends until the Session is successfully connected, including restoring all remembered subscriptions if SOLCLIENT_SESSION_PROP_REAPPLY_SUBSCRIPTIONS is enabled. Otherwise solClient_session_connect() returns SOLCLIENT_IN_PROGRESS.

See also:
Threading Effects on Blocking Modes for a discussion of blocking operation in the Context thread. Default: SOLCLIENT_SESSION_PROP_DEFAULT_CONNECT_BLOCKING
Examples:
ex/ios/examples/PerfTestExample.m, and ex/perfTest.c.
#define SOLCLIENT_SESSION_PROP_CONNECT_RETRIES   "SESSION_CONNECT_RETRIES"

How many times to try to connect to the host appliance (or list of appliances) during connection setup.

Zero means no automatic connection retries (that is, try once and give up). -1 means try to connect forever. The default valid range is >= -1.

When using a host list, each time the API works through the host list without establishing a connection is considered an connect retry. For example, if a SOLCLIENT_SESSION_PROP_CONNECT_RETRIES value of two is used, the API could possibly work through all of the listed hosts without connecting to them three times: one time through for the initial connect attempt, and then two times through for connect retries. Each connect retry begins with the first host listed. After each unsuccessful attempt to connect to a host, the API waits for the amount of time set for SOLCLIENT_SESSION_PROP_RECONNECT_RETRY_WAIT_MS before attempting another connection to a host, and the number times to attempt to connect to one host before moving on to the next listed host is determined by the value set for SOLCLIENT_SESSION_PROP_CONNECT_RETRIES_PER_HOST. Default: SOLCLIENT_SESSION_PROP_DEFAULT_CONNECT_RETRIES

Examples:
ex/common.c, ex/ios/Example.m, ex/ios/examples/PerfTestExample.m, ex/ios/examples/TopicDispatchExample.m, ex/perfTest.c, ex/RRDirectReplier.c, ex/RRDirectRequester.c, ex/RRGuaranteedReplier.c, ex/RRGuaranteedRequester.c, and ex/topicDispatch.c.
#define SOLCLIENT_SESSION_PROP_CONNECT_RETRIES_PER_HOST   "SESSION_CONNECT_RETRIES_PER_HOST"

When using a host list, this property defines how many times to try to connect or reconnect to a single host before moving to the next host in the list.

A value of 0 (the default) means make a single connection attempt (that is, 0 retries). A value of -1 means attempt an infinite number of reconnect retries (that is, the API will only try to connect or reconnect to first host listed.) NOTE: This property works in conjunction with the connect and reconnect retries Session properties; it does not replace them.

Examples:
ex/ios/examples/SecureSessionExample.m, and ex/secureSession.c.
#define SOLCLIENT_SESSION_PROP_CONNECT_TIMEOUT_MS   "SESSION_CONNECT_TIMEOUT_MS"

The timeout period (in milliseconds) for a connect operation to a given host (per host).

The valid range is > 0. Default: SOLCLIENT_SESSION_PROP_DEFAULT_CONNECT_TIMEOUT_MS

Examples:
ex/ios/examples/DirectPubSubExample.m.
#define SOLCLIENT_SESSION_PROP_GD_RECONNECT_FAIL_ACTION   "SESSION_GD_RECONNECT_FAIL_ACTION"

A property to define the behavior when the CCSMP API is unable to reconnect guaranteed delivery after reconnecting the session.

This may occur if the session is configured with a host list where each Solace router in the host list is unaware of state on the previous router. It can also occur if the time to reconnect to the same router exceeds the publisher flow timeout on the router. May be set as an environment variable (See Session Configuration Properties).
Default: SOLCLIENT_SESSION_PROP_DEFAULT_GD_RECONNECT_FAIL_ACTION

#define SOLCLIENT_SESSION_PROP_GENERATE_RCV_TIMESTAMPS   "SESSION_RCV_TIMESTAMP"

When enabled, a receive timestamp is recorded for each message and passed to the application callback in the rxCallbackInfo_t structure.

Default: SOLCLIENT_SESSION_PROP_DEFAULT_GENERATE_RCV_TIMESTAMPS

Examples:

#define SOLCLIENT_SESSION_PROP_NO_LOCAL   "SESSION_NO_LOCAL"

If this property is true, messages published on the Session cannot be received on the same Session even if the client has a subscription that matches the published topic.

If this restriction is requested, and the appliance does not have No Local support, the Session connect will fail with subcode SOLCLIENT_SUBCODE_NO_LOCAL_NOT_SUPPORTED.

Examples:
ex/noLocalPubSub.c.
#define SOLCLIENT_SESSION_PROP_OPENSSL_SECURITY_LEVEL   "SESSION_OPENSSL_SECURITY_LEVEL"

A number from 0-5 passed to the openSsl library as the security level.

#define SOLCLIENT_SESSION_PROP_PORT   "SESSION_PORT"

Deprecated.

While still supported, the port number can also now be specified as part of the host in SOLCLIENT_SESSION_PROP_HOST (for example, "hostname:55555"). In general, port numbers are not needed except in special situations, because the API chooses the correct port to connect to the appliance. If SOLCLIENT_SESSION_PROP_PORT is set, this port number is used for all entries in SOLCLIENT_SESSION_PROP_HOST that do not explicitly specify port. The port number to connect to. The valid range is 1..65535. Default: SOLCLIENT_SESSION_PROP_DEFAULT_PORT or SOLCLIENT_SESSION_PROP_DEFAULT_PORT_COMPRESSION, based on setting of SOLCLIENT_SESSION_PROP_COMPRESSION_LEVEL

When a published message is not acknowledged within the time specified for this timer, the API automatically retransmits the message. There is no limit on the number of retransmissions for any message. However, while the API is resending, applications can become flow controlled. The flow control behavior is controlled by SOLCLIENT_SESSION_PROP_SEND_BLOCKING and SOLCLIENT_SESSION_PROP_BLOCKING_WRITE_TIMEOUT_MS. The valid range is 20..60000. Default: SOLCLIENT_SESSION_PROP_DEFAULT_PUB_ACK_TIMER

#define SOLCLIENT_SESSION_PROP_PUB_WINDOW_SIZE   "SESSION_PUB_WINDOW_SIZE"

How many times to retry to reconnect to the host appliance (or list of appliances) after a connected Session goes down.

Zero means no automatic reconnection attempts. -1 means try to reconnect forever. The default valid range is >= -1.

When using a host list, each time the API works through the host list without establishing a connection is considered a reconnect retry. Each reconnect retry begins with the first host listed. After each unsuccessful attempt to reconnect to a host, the API waits for the amount of time set for SOLCLIENT_SESSION_PROP_RECONNECT_RETRY_WAIT_MS before attempting another connection to a host, and the number times to attempt to connect to one host before moving on to the next listed host is determined by the value set for SOLCLIENT_SESSION_PROP_CONNECT_RETRIES_PER_HOST. Default: SOLCLIENT_SESSION_PROP_DEFAULT_RECONNECT_RETRIES

Examples:
ex/common.c, ex/directPubSub.c, ex/ios/Example.m, ex/ios/examples/DirectPubSubExample.m, ex/ios/examples/PerfTestExample.m, ex/ios/examples/SecureSessionExample.m, ex/ios/examples/TopicDispatchExample.m, ex/noLocalPubSub.c, ex/perfTest.c, ex/RRDirectReplier.c, ex/RRDirectRequester.c, ex/RRGuaranteedReplier.c, ex/RRGuaranteedRequester.c, ex/secureSession.c, and ex/topicDispatch.c.
#define SOLCLIENT_SESSION_PROP_RECONNECT_RETRY_WAIT_MS   "SESSION_RECONNECT_RETRY_WAIT_MS"

How much time (in ms) to wait between each attempt to connect or reconnect to a host.

If a connect or reconnect attempt to host is not successful, the API waits for the amount of time set for SOLCLIENT_SESSION_PROP_RECONNECT_RETRY_WAIT_MS, and then makes another connect or reconnect attempt. SESSION_CONNECT_RETRIES_PER_HOST sets how many connection or reconnection attempts can be made before moving on to the next host in the list. The valid range is >=0. Default: SOLCLIENT_SESSION_PROP_DEFAULT_RECONNECT_RETRY_WAIT_MS.

#define SOLCLIENT_SESSION_PROP_REPLY_TO_DEFAULT_DEST   SOLCLIENT_SESSION_PROP_P2PINBOX_IN_USE
#define SOLCLIENT_SESSION_PROP_SEND_BLOCKING   "SESSION_SEND_BLOCKING"

Use SOLCLIENT_PROP_ENABLE_VAL to enable blocking send operation.

A blocking send operation suspends when the Session is transport flow controlled, otherwise the send operation returns SOLCLIENT_WOULD_BLOCK. Successful return from a blocking send operation only means the message has been accepted by the transport, it does not guarantee the message has been processed by the appliance. For the latter you must used Guaranteed Message Delivery mode and wait for the session event (SOLCLIENT_SESSION_EVENT_ACKNOWLEDGEMENT) that acknowledges the message.

Threading Effects on Blocking Modes for a discussion of blocking operation in the Context thread. Default: SOLCLIENT_SESSION_PROP_DEFAULT_SEND_BLOCKING
Examples:
ex/perfADPub.c.
#define SOLCLIENT_SESSION_PROP_SOCKET_RCV_BUF_SIZE   "SESSION_SOCKET_RCV_BUF_SIZE"

The value for socket receive buffer size (in bytes).

0 indicates do not set and leave at operating system default. The valid range is 0 or >= 1024. Default: SOLCLIENT_SESSION_PROP_DEFAULT_SOCKET_RCV_BUF_SIZE

#define SOLCLIENT_SESSION_PROP_SOCKET_SEND_BUF_SIZE   "SESSION_SOCKET_SEND_BUF_SIZE"

The value for the socket send buffer size (in bytes).

0 indicates do not set and leave at operating system default. The valid range is 0 or >= 1024. Default: SOLCLIENT_SESSION_PROP_DEFAULT_SOCKET_SEND_BUF_SIZE.

Note that Linux operating system actually allocates twice the size of the buffer requested in the setsockopt(2) call, and so a succeeding getsockopt(2) call will not return the same size of buffer as requested in the setsockopt(2) call. TCP uses the extra space for administrative purposes and internal kernel structures, and the sysctl variables reflect the larger sizes compared to the actual TCP windows.

#define SOLCLIENT_SESSION_PROP_SSL_CLIENT_CERTIFICATE_FILE   "SESSION_SSL_CLIENT_CERTIFICATE_FILE"

This property specifies the client certificate file name.

Examples:
ex/ios/examples/SecureSessionExample.m, and ex/secureSession.c.
#define SOLCLIENT_SESSION_PROP_SSL_CLIENT_PRIVATE_KEY_FILE   "SESSION_SSL_CLIENT_PRIVATE_KEY_FILE"

This property specifies the client private key file name.

Examples:
ex/ios/examples/SecureSessionExample.m, and ex/secureSession.c.
#define SOLCLIENT_SESSION_PROP_SSL_CLIENT_PRIVATE_KEY_FILE_PASSWORD   "SESSION_SSL_CLIENT_PRIVATE_KEY_FILE_PASSWORD"

This property specifies the password used to encrypt the client private key file.

Examples:
ex/ios/examples/SecureSessionExample.m, and ex/secureSession.c.
#define SOLCLIENT_SESSION_PROP_SSL_CONNECTION_DOWNGRADE_TO   "SESSION_SSL_CONNECTION_DOWNGRADE_TO"

This property specifies a transport protocol that SSL connection will be downgraded to after client authentication.

Allowed transport protocol is "PLAIN_TEXT". May be combined with non-zero compression level to achieve compression without encryption.

Examples:
ex/ios/examples/SecureSessionExample.m, and ex/secureSession.c.
#define SOLCLIENT_SESSION_PROP_SSL_EXCLUDED_PROTOCOLS   "SESSION_SSL_EXCLUDED_PROTOCOLS"

This property specifies a comma separated list of excluded SSL protocol(s).

Valid SSL protocols are 'SSLv3', 'TLSv1', 'TLSv1.1', 'TLSv1.2'. Default: SOLCLIENT_SESSION_PROP_DEFAULT_SSL_EXCLUDED_PROTOCOLS.

Examples:
ex/ios/examples/SecureSessionExample.m, and ex/secureSession.c.
#define SOLCLIENT_SESSION_PROP_SUBCONFIRM_TIMEOUT_MS   "SESSION_SUBCONFIRM_TIMEOUT_MS"

The timeout period (in milliseconds) for subscription confirm (add or remove).

The valid range is >= 1000. Default: SOLCLIENT_SESSION_PROP_DEFAULT_SUBCONFIRM_TIMEOUT_MS

#define SOLCLIENT_SESSION_PROP_SUBSCRIBE_BLOCKING   "SESSION_SUBSCRIBE_BLOCKING"

Use SOLCLIENT_PROP_ENABLE_VAL to enable blocking subscribe/unsubscribe operation.

A blocking subscribe operation will suspend when the Session is transport flow controlled, otherwise the subscribe operation returns SOLCLIENT_WOULD_BLOCK. A successful return from a blocking subscribe operation only means the subscription has been accepted by the transport, it does not guarantee the subscription has been processed by the appliance. For the latter you must use a confirmed operation (see SOLCLIENT_SUBSCRIBE_FLAGS_WAITFORCONFIRM)

See also:
Threading Effects on Blocking Modes for a discussion of blocking operation in the Context thread. Default: SOLCLIENT_SESSION_PROP_DEFAULT_SUBSCRIBE_BLOCKING
Examples:
ex/perfTest.c.
#define SOLCLIENT_SESSION_PROP_TCP_NODELAY   "SESSION_TCP_NODELAY"
#define SOLCLIENT_SESSION_PROP_TOPIC_DISPATCH   "SESSION_TOPIC_DISPATCH"
#define SOLCLIENT_SESSION_PROP_TRANSPORT_PROTOCOL_DOWNGRADE_TIMEOUT_MS   ("SESSION_TRANSPORT_PROTOCOL_DOWNGRADE_TIMEOUT_MS")

Specifies how long to wait (in milliseconds) for a login response before moving to the next available protocol in a user specified or the default WEB Transport Protocol downgradelist.

Default SOLCLIENT_SESSION_PROP_DEFAULT_TRANSPORT_PROTOCOL_DOWNGRADE_TIMEOUT_MS

#define SOLCLIENT_SESSION_PROP_UNBIND_FAIL_ACTION   "SESSION_UNBIND_FAIL_ACTION"

A property to define the behavior if an unbind-response is not received after an unbind-request (solClient_flow_destroy()) is sent to the Solace Appliance.

If this occurs it is possible that the endpoint may be still bound and unavailable until the session is terminated. In this occurrence the session can be configured to retry sending the unbind-request or to fail the session transport. If the sesion transport fails, the session will behave as defined by the SOLCLIENT_SESSION_PROP_RECONNECT_RETRIES configuration. Default: SOLCLIENT_SESSION_PROP_DEFAULT_UNBIND_FAIL_ACTION.

#define SOLCLIENT_SESSION_PROP_USER_ID   "SESSION_USER_ID"

A read-only informational string providing information about the application, such as the name of operating system user that is running the application, the hostname, and the PID of the application.

#define SOLCLIENT_SESSION_PROP_VIRTUAL_ROUTER_NAME   "SESSION_VIRTUAL_ROUTER_NAME"

A read-only property that indicates the connected appliance's virtual router name.

Appliance endpoint and destination names created with a virtual router name are valid for use with that appliance, or to address destinations on remote appliances (in a multiple-appliance network) when publishing messages. Applications requiring the virtual router name do not need to poll this property every time it is required, and they may cache the name. Applications should query the name once after connecting the Session, and again after a reconnect operation reports the SOLCLIENT_SESSION_EVENT_VIRTUAL_ROUTER_NAME_CHANGED event. Prior to connecting, an empty string is returned.

#define SOLCLIENT_SESSION_PROP_VPN_NAME_IN_USE   "SESSION_VPN_NAME_IN_USE"

A read-only Session property that indicates which Message VPN the Session is connected to.

When not connected, an empty string is returned.

#define SOLCLIENT_SESSION_PROP_WEB_TRANSPORT_PROTOCOL   ("SESSION_WEB_TRANSPORT_PROTOCOL")

This property specifies a WEB Transport Protocol in the default WEB Transport Protocol downgrade list to use for the session connection.

Valid values are transportProtocol. Default: SOLCLIENT_SESSION_PROP_DEFAULT_WEB_TRANSPORT_PROTOCOL If the connection fails, the API will try to connect using the next (less efficient) availabe protocol in the list until it finds one that works. If there is none available, then the session connection fails.

#define SOLCLIENT_SESSION_PROP_WEB_TRANSPORT_PROTOCOL_IN_USE   ("SESSION_WEB_TRANSPORT_PROTOCOL_IN_USE")

Read-only property which returns the WEB Transport Protocol currently in use for web messaging.

An empty string is returned when a session is not connected or it is not a web messaging session. Valid values are transportProtocol. Valid values are transportProtocol.

#define SOLCLIENT_SESSION_PROP_WEB_TRANSPORT_PROTOCOL_LIST   ("SESSION_WEB_TRANSPORT_PROTOCOL_LIST")

This property specifies a comma separated list of WEB Transport Protocols to use for session connection.

The API will use the first one in the list to start session connection. If the connection fails, the API will try to connect using the next available protocol in the list until it finds one that works. If there is none available, then the session connection fails. Note: Only one of the session properties SOLCLIENT_SESSION_PROP_WEB_TRANSPORT_PROTOCOL and SOLCLIENT_SESSION_PROP_WEB_TRANSPORT_PROTOCOL_LIST is allowed to be configured. There shall be no duplicates in the list.
